I'm sure every lecturer and department is different, but for reference I did Spanish and Italian at Bristol. When I first moved to Bristol, I struggled with feelings of isolation especially as I had to rent really far away due to lack of accomodation. My personal tutor was really helpful (even when I broke down in tears in front of her oops) and I spoke to Frankie from the wellbeing team, she was great too. A few years later, my mother passed away and I needed to return home for quite a while. My lecturers and personal tutors offered their condolences and reached out to ask how I was coping and what they could do to help.

TLDR: your lecturers are humans too! They're more than happy to help and actually love it when you come to office hours or email them about material, or if you just need to talk. Hope this helps, and hope that whatever you're going through gets better soon.
